摘要：
本实用新型提供了一种自动扫频滤波器，所述自动扫频滤波器包括谐振棒组件、腔体、步进电机、光电探测器、拉杆、簧片和盖板。本实用新型的自动扫频滤波器的优点在于当要改变滤波器的工作频率时，只要轻轻一按，滤波器很快就能自动调整到需要的工作频率。
摘要（英）：

The utility model provides an automatic frequency sweep filter. The automatic frequency sweep filter comprises a resonant rod assembly, a cavity, a stepping motor, a photoelectric detector, a pull bar, a reed and a cover plate. The advantages of the automatic frequency sweep filter are that if the work frequency of the filter needs to be changed, the filter can be rapidly and automatically adjusted to be under the needed work frequency as long as the filter is pressed slightly.
